Cracks in your walls, floors, or foundation are more than just an eyesore—they could be a warning sign of deeper structural issues. Some cracks are harmless, while others indicate significant problems that require immediate attention. At Crack & Attic Doctor, we help homeowners across Calgary and surrounding areas diagnose and repair cracks before they become a costly disaster.
Let’s explore the different types of cracks, what they mean, and when you should take action.
1. Hairline Cracks (Minimal Concern)
🔹 What They Look Like: Thin, barely visible cracks in drywall or concrete.
🔹 What Causes Them: Normal settling, drying shrinkage, or minor temperature changes.
🔹 Should You Worry? Not usually. Keep an eye on them, and if they expand, call a professional.
2. Vertical Cracks (Common but Monitor Closely)
🔹 What They Look Like: Cracks running straight up and down.
🔹 What Causes Them: Natural foundation settling over time.
🔹 Should You Worry? If the crack is narrow (less than 1/8 inch) and doesn’t grow, it’s not an immediate threat. However, if it widens or water starts seeping through, professional repair is necessary.
3. Diagonal Cracks (Could Indicate Foundation Movement)
🔹 What They Look Like: Cracks at a 30–75-degree angle, often wider at one end.
🔹 What Causes Them: Uneven settling of the foundation or soil shifting beneath your home.
🔹 Should You Worry? Yes. These cracks can worsen over time and may require professional crack repair to prevent further structural issues.
4. Stair-Step Cracks (Serious Foundation Concern)
🔹 What They Look Like: A stair-step pattern in brick or block walls.
🔹 What Causes Them: Differential foundation settling, often due to soil expansion and contraction.
🔹 Should You Worry? Yes. This type of crack is a clear sign of foundation stress and needs professional attention before structural damage worsens.
5. Horizontal Cracks (Urgent Structural Warning)
🔹 What They Look Like: Cracks running parallel to the ground.
🔹 What Causes Them: Excessive lateral pressure from soil or water buildup against the foundation.
🔹 Should You Worry? Absolutely. Horizontal cracks indicate severe foundation stress and can lead to wall failure if left untreated. Immediate professional repair is required.
6. Floor Cracks (May Indicate Settlement Issues)
🔹 What They Look Like: Cracks appearing on basement or garage floors.
🔹 What Causes Them: Soil movement, hydrostatic pressure, or improper concrete curing.
🔹 Should You Worry? Minor cracks are common, but large or widening cracks may indicate deeper foundation problems and should be assessed.
7. Cracks Around Windows and Doors (Sign of Shifting Foundation)
🔹 What They Look Like: Cracks that radiate from window and door frames.
🔹 What Causes Them: Foundation movement causing stress on framing materials.
🔹 Should You Worry? If you also notice sticking doors and windows, it’s a sign that your foundation is shifting. Professional evaluation is recommended.
What to Do If You Spot a Crack
🔍 Monitor Small Cracks: If they stay the same size, they may not be a concern.
📏 Measure Width and Growth: If a crack widens over time, it’s time to take action.
💧 Check for Water Leaks: Moisture coming through cracks can lead to mold and further damage.
🏠 Call a Professional: If you’re unsure, it’s always best to get an expert opinion.
